10, the tubulose nozzle-end tube wall between elastic card claw, which upwardly extends, is higher by flange upper surface formation baffle, can incite somebody to action Under part fertilizer gear axially movable, farmland is sprayed to from tubulose spout, keeps spray fertilizer amount uniform.

11, hoisting mechanism is set, the height of present invention spray spray fertilizer operation can be adjusted in time as needed.

12, nozzle connection is connected to the side of boom pipe, communicates from side with boom pipe, in this way can be quick by nozzle connection It is assembled on boom pipe, without dismantling boom pipe when needing replacing nozzle connection.

13, between pipe-supporting bar, bearing support be floating connecting structure, in this way, the present invention on rugged road or It walks in farmland, rack can tilt, at this point, pipe-supporting bar is automatically adjusted to basic horizontal state in Gravitative Loads lower swing, Basic horizontal state can be adjusted without complicated mechanism.

14, the first gag lever post is set, swing pipe-supporting bar can only in vertical plane, limits front-rear direction of the present invention Pipe-supporting bar is moving in the front-back direction when inclination, and effective protection pipe-supporting bar significantly prolongs its service life.

15, the anti-swing device that setting prevents pipe-supporting bar from swinging, can fix pipe-supporting bar according to need of work, Prevent its swing.

16, equipped with the telescoping mechanism to stretch for side spray fertilizer piping support bar, so that it may easily stretch, meet spray Spray fertilizer operation and the different of walking need.

17, telescoping mechanism is driven by mechanical driving mechanism, is stretched quick, efficiently.

18, setting rear-axle steering driving device is, it can be achieved that four-wheel steering, to substantially reduce turning radius, front and rear wheel can To walk out the track trace of same Radius, track trace is substantially reduced, the be collapsed caused by crops will be fewer in this way.

19, the present invention can carry out front-wheel according to different requirements, four-wheel steering is switched fast.

20, sensor, vane are designed in vehicle bridge component, in use, if will front-wheel steer and four-wheel steering it Between switch over, if front-wheel or rear-wheel do not return just, the power cylinder of steer-drive is in the lock state；When front-wheel, Afterwards after circulation just, sensor detects the information that vane issues, and sensor transfers signals to control system, control system hair Signal out opens the power cylinder of steer-drive, carries out the switching of front-wheel steer and four-wheel steering, therefore, is equipped with sensing system System can more reliable, safely carry out the switching of front-wheel steer and four-wheel steering, prevent safety accident.
